Which statement is true?

  • The probability that a randomly selected silver medal was awarded to Great Britain is StartFraction 17 Over 99 EndFraction.
  • The probability that a randomly selected medal won by Russia was a bronze medal is StartFraction 32 Over 103 EndFraction.
  • The probability that a randomly selected gold medal was awarded to China is StartFraction 88 Over 137 EndFraction.
  • The probability that a randomly selected medal won by the United States was a silver medal is StartFraction 104 Over 339 EndFraction.

Answer:

(A)The probability that a randomly selected silver medal was awarded to Great Britain is 17/99.

Step-by-step explanation:

The table is given below:

\left|\begin{array}{l|c|c|c|c|c}  &Gold&Silver          & Bronze       &Total\\United States    &46      &    29      &          29      &         104\\China             &     38     &     27       &         23        &         88\\Russia         &        24  &        26      &          32                 &82\\Great Britain   &    29   &        17        &        19        &         65\\&&&&&\\Total                    &137     &     99     &          103      &        339\end{array}\right

                         

We calculate the probabilities given in the statements.

(A) The probability that a randomly selected silver medal was awarded to Great Britain

= 17/99

(B)The probability that a randomly selected medal won by Russia was a bronze medal

=32/82

(C)The probability that a randomly selected gold medal was awarded to China

=38/137

(D)The probability that a randomly selected medal won by the United States was a silver medal

=29/104

We can see that only the first statement is true.

What are the y-intercepts to graph the equation-4x - 3y = 36
Eddi Din [679]

Answer:

Y-Int = -12

Step-by-step explanation:

First, I would change the equation to slope intercept form:

-3y = 36 + 4x

3y = -36 - 4x

y = -12-4/3x

y = -4/3x - 12

In the diagram below, ΔABC ∼ ΔDEF. If AC=18,BC=24. and DF=12, find EF
ValentinkaMS [17]

Answer:

9

Step-by-step explanation:

similar triangles.

that means there is one common factor to transform the lengths of all lines from one triangle to the other.

it looks to me DF is the longest side in DEF, and that would make it associated to BC of ABC.

so, the factor is then

BC = DF×f

24 = 12×f

=> f = 2

so, EF then is associated to AC.

AC = EF × f

18 = EF × 2

EF = 18/2 = 9
